MCQ
Which is not the characteristic of $\pi−$ bond?
  • A
    $\pi$ bond is formed when a sigma bond already exists.
  • ✓
    $\pi$ bonds are formed from hybrid orbitals.
  • C
    $\pi$ bond may be formed by the overlapping of p orbitals.
  • D
    $\pi$ bond results from lateral overlap of atomic orbitals.
✓

Answer

Correct option: B.
$\pi$ bonds are formed from hybrid orbitals.
$\pi$ bond is formed between two atoms if a sigma bond already exists between them.
$\pi$ bonds are formed only by pure orbitals $(p−$ orbitals$),$ not from hybrid orbitals.
